8# @BLURB: many extra (but common) functions that are used in ebuilds
9# @DESCRIPTION:
10# The eutils eclass contains a suite of functions that complement
11# the ones that ebuild.sh already contain. The idea is that the functions
12# are not required in all ebuilds but enough utilize them to have a common
13# home rather than having multiple ebuilds implementing the same thing.
14#
15# Due to the nature of this eclass, some functions may have maintainers
16# different from the overall eclass!

117# 02_sparc_another-fix.patch.bz2

119# This ensures that there are a set order, and you can have ARCH
120# specific patches.
121#
122# If you however give an argument to epatch(), it will treat it as a
123# single patch that need to be applied if its a file. If on the other
124# hand its a directory, it will set EPATCH_SOURCE to this.

1663# @FUNCTION: built_with_use
1664# @USAGE: [--hidden] [--missing <action>] [-a|-o] <DEPEND ATOM> <List of USE flags>
1665# @DESCRIPTION:
1666# A temporary hack until portage properly supports DEPENDing on USE
1667# flags being enabled in packages. This will check to see if the specified
1668# DEPEND atom was built with the specified list of USE flags. The
1669# --missing option controls the behavior if called on a package that does
1670# not actually support the defined USE flags (aka listed in IUSE).
1671# The default is to abort (call die). The -a and -o flags control
1672# the requirements of the USE flags. They correspond to "and" and "or"
1673# logic. So the -a flag means all listed USE flags must be enabled
1674# while the -o flag means at least one of the listed IUSE flags must be
1675# enabled. The --hidden option is really for internal use only as it
1676# means the USE flag we're checking is hidden expanded, so it won't be found
1677# in IUSE like normal USE flags.
1678#
1679# Remember that this function isn't terribly intelligent so order of optional
1680# flags matter.
